INCANDESCENT VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 648,993, dated May 8,1900. Application filed July 10, 1899. Serial No. 723,285. (No model.)

To all whom it may concern.-

Be itknown that I, LEROY S. PFOUTS, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in IncandescentVapor-Burners; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, and to thefigures of reference marked thereon, in which Figure 1 is a sideelevation showing all the parts properly connected. Fig. 2 is a detachedview of the generator. Fig. 3 is a sectional view through line 3 y, Fig.2. Fig. 4 is a sectional view of the lamp proper. Fig. 5 shows a portionof the burner. Fig. 6 is a view showing a portion of the gas-pipe andillustrating the pivoted arm connected thereto. Fig. 7 is a view showingthe generator, feed-pipe, and the gas-conveying pipe, showing thegenerator in'a reversed position from that shown in Fig. 2. Fig. 8 is atransverse view on line w m, Fig. 3. of the generator with the plugremoved.

The present invention has relation to incandescent vapor-burners; and itconsists in the difierent parts and combination of parts hereinafterdescribed, and particularly pointed out in the claims.

Similar numerals of reference indicate c0rresponding parts in all thefigures of the drawings.

In the accompanying drawings, 1 represents the tank, which may be of anysize or kind and from which tank leads the supply-pipe 2, to whichsupply-pipe is connected the horizontal feed-pipe 3, which feed-pipe isprovided with the valve 4. To the end of the feed-pipe 3 is connectedthe vaporizing-pipe 5, which vaporizing-pipe 5 is provided with the twobores or passages 6 and 7, said passages being of different diametersand are formed of different diameters for the purpose hereinafterdescribed. To the extreme end of the vaporizing-pipe 5 is connected theplug 8, said plug being so located that it will form a chamher 9 at theends of the passages 6 and 7.

The vaporizing-pipe 5 is provided with any Fig. 9 is an end view.

desired number of fins or bars 10, said fins or bars being preferablylocated as illustrated in the drawings; but it will be understood thatthe purpose of said fins, hereinafter described, can be carried outwithout any particular reference to the exact location and arrangement.It will be understood that by providing the fins or bars 10 they will beheated, thereby increasing the degree of heat in the vaporizing-pipe 5.

The fuel is fed from the su pply-iank through the feed-pipe and throughthe bore 6,'said bore being the one having the lesser diameter, the fuelbeing conveyed to the chamber 9, and from which chamber it enters thepassage 7, said passage 7 being formed of greater diameter, so as toprovide for the increase bulk of the fuel after it has become convertedinto gas, thereby providing for expansion. After the fuel has enteredthe passage 7 it is conveyed to the needle-chamber 11, whichneedlechamber is formed of increased diameter, thereby increasing thesize and capacity, and by so doing a reserve supply of fuel, therebyproducing a uniform and steady flow into the mixing-tube without anyparticular reference to the amount of fuel or the regularity of the flowof the fuel from the tank 1.

The mixing-tube or gas-pipe 12 is substantially-ot' the form shown, and,asshown, its upper end is located a short distance away from theneedle-chamber l1 and its needle v13, by which arrangement the properamount 'of air is supplied or mixed with the fuel.

attached the arm 16, the free end of said arm .be understood that aburner of some kind 10o must be employed to carry out the object andpurpose of the present invention.

\Vhen it is desired to turn the burner 19, together with the differentparts belonging thereto, out of the way or from under the generator, thetube 18, together with the burner, is lifted up, so as to clear itsbottom or lower end from the elbow lat, after which the arm 16 is freeto be turned upon its pivotal point, said arm carrying and supportingthe burner.

It will be understood that when the burner has been turned to one side,as just above described, the lamp will be out from under the generator,at which time said generator can be conveniently heated for the purposeof starting the lamp, and another object-for providing for turning thelamp from under the generator is to provide an easy and convenient wayof connecting the mantle 20, chimney 21, and shade 22.

For the purpose of providing, a suitable support for the feed-pipe 3,together with the vaporizing-pipe 5 and its different parts, themixing-pipe 12 is provided with the post 23, said post forming a supportfor the parts above named.

It will be understood that the lamp may be supported by the arm or arms2% or it may be suspended by means of the hook 25.

For the purpose of confining the heat the bell-shaped cone 26 isprovided and is located directly 'over the fins or arms 10, saidbellshaped cone being supported by means of the post 27, which post isconnected to the upper side of the vaporizing-pipe 5.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an incandescent vapor-burner, a vaporizing-pipe normally locatedover the lamp, bores or passages of diiterent diameters formed in thevaporizing-pipe, one of said passages communicating with the supplypipe,and the other communicating with the needle-chamber 11 and both of saidbores or passagescommunicating with the chamber 9 formed in thevaporizing-pipe, fins located upon the vaporizing-pipe and aneedle-chamber communicating with the bore or passage having the largerdiameter, and a mixingtube, substantially as and for the purposespecified.

2. In an incandescent vapor-burner, a mixing-tube having pivotallyconnected thereto an arm provided with an eye, a burner provided with atube located through the eye and normally seated into the elbow of themixing-tube, substantially as and [or the purpose specified.

3. In an incandescent vapor-burner, a pivoted arm provided with an eye,a burner to be located through the eye and normally seated into thelower end of the mixing-tube, and the mixing-tube, substantially as andfor the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
